| michael@0 | 9 | * Description: |
| michael@0 | 10 | * This test runs in conjunction with the sockping test. |
| michael@0 | 11 | * The sockping test creates a socket pair and passes one |
| michael@0 | 12 | * socket to this test. Then the sockping test writes |
| michael@0 | 13 | * "ping" to this test and this test writes "pong" back. |
| michael@0 | 14 | * To run this pair of tests, just invoke sockping. |
| michael@0 | 15 | * |
| michael@0 | 16 | * Tested areas: process creation, socket pairs, file |
| michael@0 | 17 | * descriptor inheritance. |
